Dometic Penguin II Ceiling Assembly for Non-Ducted Installations with Wall Thermostat - Pre-Installed Single Zone

What is the Dometic Penguin II ceiling assembly for non-ducted installations?

This is the lower ceiling assembly that mounts inside your RV beneath a Dometic Penguin II rooftop air conditioner in a non-ducted setup. It includes the return air grille, filter, and integrated controls for a single-zone system with a pre-installed wall thermostat connection. The non-ducted configuration pulls return air through the ceiling assembly itself and discharges cooled air directly into the living space, which is the standard arrangement in most travel trailers and smaller fifth wheels.

How do I know if I need a non-ducted ceiling assembly versus a ducted one?

Look at your RV ceiling. If cooled air comes out of the ceiling assembly directly below the rooftop unit, you have a non-ducted system and need this assembly. If cooled air is distributed through vents in different parts of the coach via ductwork in the ceiling, you have a ducted system and should look at the Coleman Power Saver HP ceiling assembly for ducted installations or a comparable Dometic ducted option. Always confirm your existing rooftop unit model number before ordering.

Does this ceiling assembly work with a wall thermostat?

Yes. This single-zone configuration is built for wall thermostat control rather than ceiling-mounted controls. The thermostat wiring harness is pre-installed at the assembly, so you connect to a compatible Dometic wall thermostat (typically the CCC2 or comparable single-zone unit) during installation. Confirm your thermostat part number against the Dometic compatibility list before ordering to avoid a control mismatch.

What other Penguin II compatible parts and ceiling assemblies do you carry?

We stock Penguin II rooftop units, replacement shrouds, gaskets, capacitors, and control boards alongside ceiling assemblies for other Dometic and Furrion units. If you have a different rooftop unit, see the FreshJet 5 with heat pump ceiling assembly or the Furrion Original ceiling assembly for non-ducted installations. Need help confirming fitment?

How does shipping work on ceiling assemblies?

Ceiling assemblies ship via standard ground freight from our warehouse. Orders over $100 qualify for free shipping. Larger AC components occasionally ship via truck freight depending on packaging dimensions, which will be noted on the product page. Verify your model and thermostat compatibility before placing the order to avoid return freight on an oversized item.
